Cape Fear Community College students are utilizing the E-BikeKit™ electric bike kit in the designing and building of their own electric bicycles!   ORIGINAL ARTICLE POSTED by the Port City Daily staff "CFCC student-built electric bikes to be in Azalea Fest parade Some innovative designs by Cape Fear Community College students will be featured in this year’s N.C. Azalea Festival. For the past year, students in CFCC’s mechanical engineering program have been hard...
Some power-on-demand only e-bikes can hardly be confused with, let alone categorised as, bicycles. For example, the Noped is a term used by the Ministry of Transportation of Ontario for e-bikes which do not have pedals or in which the pedals have been removed from their motorised bicycle. These are better categorised as electric mopeds or electric motorcycles.
This bike is named the GSD because with it you can Get Stuff Done. Twenty-inch wheels keep the center of gravity low so heavy payloads—it's rated up to 400lbs—are easy to balance and a short (for a cargo bike) 70-inch wheelbase, similar to a standard single bike, make the GSD easy to maneuver. Designed with the urban commuter in mind, the bike can easily break down to 60 percent of its original size to fit into the back of a car and the rear rack doubles as a stand that allows it to stand upright to minimize space inside tight apartments. Put two child seats on the back and take the family along, or drop the seat and let you kid take the bike out himself—anyone from 4'10" to 6'5" can ride this bike. Last but not least, the GSD gives you the option of adding a second battery to extend your range up to about 150 miles on a single charge.
**The eBike uses a quick-release battery system. Lightweight 200Wh Lithium-ion battery packs can be swapped in seconds at the roadside. Each pack weighs just 1.4Kg, so spare battery packs can easily be carried for longer trips. The range that can be achieved from each pack will vary according to the conditions and effort exerted by the rider. Ranges of around 30 miles are normal per each full eBike battery charge. Less fit riders may achieve ranges of 10 miles or less, particularly in challenging conditions like steep hills, strong head-winds or soft terrain. The conditions which affect the range are rider fitness, weight, size and seating position, head or tail winds, gradient, terrain, tyre pressure, what gear is used, number of stop/starts and the speed the bike is ridden.
I'm looking to leverage the Cycle to Work Scheme and have been looking around for an e-bike to purchase. I used a lot of the information provided here and have come to the conclusion that the Kreiger from Woosh meets all my needs. 95% of the time the bike will be used to commute to and from work, the rest of the time I'll probably be rising it around the park with the kids. The thing I like about this bike is that it pretty much comes with everything (except the lock) that you'd need to get going. I guess, if I really wanted to, I could upgrade the Bafang motor on this to a BBS02 with a better battery.

Me: I had a total of seven knee surgeries over 14 months, and man, my fitness took a beating. Getting back on a bike was both liberating and frustrating. I just can’t go as fast, or as far, as I used to. But, you don’t have to fall victim to a flesh-eating bacterial infection during routine a ACL reconstruction to find the idea of an electric mountain bike appealing. 
The Spectral:ON 7.0 helps you to try new ways, to shift boundaries and to sit in the saddle more often. The Enduro configuration with rigid RockShox Lyrik RC suspension fork and RockShox Deluxe R shocks tames the roughest trails. The E-MTB-specific DT Swiss H1700 Spline wheels are fitted with robust Maxxis Minion tyres that offer maximum grip and control downhill. The Shimano Zee brakes from the freeride sector with 200 mm large brake discs at the front and rear are very powerful - there is no more control and safety in this class. The 165 mm short cranks guarantee the best possible ground clearance. The Kind Shock Lev Integra SI Vario seat post can be lowered at the push of a button when it gets steep. All in all, the Spectral:ON 7.0 is your ticket to trails that otherwise might not have been accessible.

The time or distance an electric bike battery will run between chargings is impossible to judge with much accuracy. There are too many variables: terrain, speed, rider weight, bike load (shopping, kids, luggage), and more. However, we can make a few generalizations about an e-bike’s recharge time and overall working life. These generalizations should be used for comparison purposes only.
Mountain bikers and their associations (which I used to be a proud member of), should reconsider their anti-eMTB stance, realize there is a need and demand for Type 1 eMTBs, and focus their efforts on keeping trails open for all mountain bikes. Mountain bikers deserve the right to ride more of our public trails than we are currently allowed. I won’t open a can of worms with my strong opinions on where I believe mountain bikes should be allowed, but suffice it to say that we don’t have near enough access as we should.
I have been mountain biking since the late 1980s, when all I could afford was an entry-level Bridgestone MB-5 on my strapped college budget. Over the years, I’ve explored up and down the mountains of Washington and Oregon in search of the best singletrack. The bikes changed but our passion ebbed not. When I co-founded Trails.com in the late 1990s, mountain biking was still one of my top outdoor pursuits. Our employees were outdoors nuts as well and biking was simply a part of life.
Direct-to-consumer Italian brand Thok’s MIG bike has reviewers falling at its feet. Why? It simply offers a superb package – its geometry and construction are as on-the-ball as its choice of Shimano motor, battery placement – giving low centre of gravity – and quality build kit. At under £4k, the MIG is great value too (there is also a pricier MIG R, featuring upgraded components). Thok knows its stuff, which is hardly surprising when you look at its founder. Former champion downhill racer Stefano Migliorini understands what makes a good bike, and he personally leads the charge on bike development at Thok.

Combined with our network of partner bike shops around the country for on-the-ground support, you are covered for anything a bike path can throw at you.
In addition, Kalk weighs under 155 pounds — less than half of traditional motorbikes. Cake customized parts of the drivetrain and implemented an interior permanent magnet (IPM) motor. On a single charge, the bike travels up to 50 miles and as a bonus feature, maintenance is minimal due to the fact there are few moving parts thanks to its lack of a combustion engine.

While we’re on this thread, I want to go ahead and throw in the most tricked-out shred sled in the AllMtn line. Haibike spared no expense wit the XDURO AllMtn 10.0. It’s a premium bike, and here is why. A Fox Factory 34 front suspension fork with 150mm of travel and Kashima coating starts things off. That’s followed by a 20-speed drivetrain brought to you by Shimano Deore XT Shadow Plus. Then you’ve got DT Swiss rims, KS LEV-DX dropper seatpost, Magura MT7 HD brakes, and a Yamaha PW-X motor. ‘Nuff. Said.
Motor: We have a blog post showing some motor differences: https://www.ebikekit.com/blogs/news/its-whats-inside-your-motor-that-counts Cabling is probably the #1 issue when something goes wrong. Good connectors, good cables, and good assembly (bike shop!) are crucial Strain reliefs on all cable joints! Where you have a junction box or a connector, the stress is concentrated over a small area near this stiff spot on the cable. This can cause small breaks on the internal...
Consider, too, that more than half of all driving trips are shorter than 10 miles, with some surveys reporting that the average single trip amounts to just 5.95 miles. That’s a no-brainer distance to cover by e-bike. In fact, the survey found that owners replaced 46 percent of their car commutes and 30 percent of their driving errands with e-bike rides. All you need is a great commuter bag to carry your stuff, and you’re set.
Ethics aside, that’s not to say we don’t at least admire where the technology has taken us thus far – and where it appears to be heading- thanks to some of the best electric mountain bikes on the market today. Some, naturally, are more rugged and built to withstand greater beatings than others. While some feature a price tag similar to that of a new Harley-Davidson. Whatever the case, if the disposable income is there, as well as the integrity not to abuse the power these electric machines offer, then they’re certainly yours for the taking. Just have a look at our eight favorite picks below and see for yourself.
The Espin is powered by a 350-watt motor that’s rated for trips up to 50 miles (depending on the terrain and assist level). Once depleted, the battery fully charges in roughly five hours. Thankfully, Espin makes it easy to remove the battery, allowing you to quickly recharge it at home or in the office between trips. A backlit LCD control hub displays your basic metrics and battery life while in transit and LED headlights add a touch of light when needed.

On mine I got the Topeak front and SKS rear mud guards, an Axiom rear rack, front and rear lights. They didn’t have a headlamp with the lumens I wanted, so Tommy the owner went ahead and ordered one for me! He was always available for any question I may have had through his mobile phone, and updated me with pictures showing me different possible setups to see if I would like it.
In addition to the pedal-assist feature, some e-bikes come with a throttle that engages the motor with the press of a button. These belong to a separate class of e-bike that, obviously, doesn’t offer a pure cycling experience; they’re also illegal in some municipalities. Interestingly, Benjamin says, people who aren’t already “cyclists” tend to gravitate toward throttle bikes at first, but then turn around and choose a pedal-assist for their next purchase.
Electric trikes have also been produced that conform to the e-bike legislation. These have the benefit of additional low speed stability and are often favored by people with disabilities. Cargo carrying tricycles are also gaining acceptance, with a small but growing number of couriers using them for package deliveries in city centres.[51][52] Latest designs of these trikes resemble a cross-between a pedal cycle and a small van.[53][54]
Electric Bike Conversion Kits are prepackaged sets of components designed to fit on a normal bike and convert it into an Electric Bike. These kits make it easier for end-users to find compatible, functioning parts and purchase them all together. A kit can range from a complete system that includes all the small parts you need, to DIY kits that include only a few parts and leave the rest up to the user.
In the end, the Specialized Turbo Levo FSR Comp 6Fattie proved to be the tester favorite, offering the best downhill performance that felt the "most like a mountain bike" that the other models couldn't match. The Specialized proved to be the most nimble and agile by far, with the lowest center of gravity, shortest wheelbase, less rear wheel travel, and shortest reach, yet still managed to be confident and stable at speed. By contrast, the Commencal Meta Power Race 650B+, our Top Pick for Aggressive Riders, felt much more one-dimensional with its long and slack geometry and ultra plush suspension, excelling at speed, but sluggish at lower speeds or technical downhill sections. The HaiBike XDURO AllMtn 8.0 proved to be a less inspiring downhill performer, with a massive feel, rattling battery, and a generally unrefined feel, although it was good at going straight and fast. The Trek Powerfly 7 FS was our least favorite e-bike to ride downhill, with a less impressive component specification that held it back and didn't inspire confidence on descents.
Basically, there is no reason to ride an eMTB with less than 130 mm of travel. With classic bikes, more travel usually means both less efficiency and poorer climbing characteristics, but this is not true with eMTBs – at least not up to a certain point. The best example is the Specialized Turbo Levo, which with its 135 mm of travel at the rear handles much better than most of the other, longer travel bikes in the group test. Also, eMTBs with suspension travel of 180 mm or more are often noticeably less efficient, as clearly exemplified in this test by the Haibike XDURO Nduro. It climbs a lot slower than other bikes using the same motor and the same level of assistance, an experience you will find with almost all other long-travel bikes from other manufacturers. The exception is the BULLS E-CORE EVO EN Di2: in direct comparison, it climbs a lot more efficiently, even though it also offers 180 mm of travel. The ideal compromise between uphill and downhill performance usually lies somewhere between 130 and 160 mm of travel.

The Moterra is Cannondale’s biggest and baddest e-mtb and just looking at this thing you can see that it’s built to withstand some wicked downhills and big drops. With 130mm of front and rear travel, paired up with 27.5-inch wheels and trail-grabbing 2.8-inch tires, along with a KS LEV Integra Dropper Post make this pedal-assist mountain bike a great option if you want to climb farther to shred longer, but don’t want to lug your bike uphill for ages. The 250w motor, placed slightly farther forward than most other bikes to optimize weight distribution and handling, will give you a nice boost so you can enjoy the ride up and not be too gassed when you get to the top. After all, it’s all about the ride down, right?
It is important to note that the less power you use while riding your e-bike, the longer the battery will last, makes sense right? All of the pedal-assist drive units we tested also have smartphone apps that can be used to customize your support settings, and such changes may allow for more or less range on your electric mountain bike. Specialized's Mission Control app has a feature that lets you set a predetermined route, and the app then regulates the motor's support to ensure power lasts to finish your ride.

In a parallel hybrid motorized bicycle, such as the aforementioned 1897 invention by Hosea W. Libbey, human and motor inputs are mechanically coupled either in the bottom bracket, the rear wheel, or the front wheel, whereas in a (mechanical) series hybrid cycle, the human and motor inputs are coupled through differential gearing. In an (electronic) series hybrid cycle, human power is converted into electricity and is fed directly into the motor and mostly additional electricity is supplied from a battery.
